When is the last time you saw something like that carried around that wasn't a rerun of "Cops" recorded in '89? Today you see telescoping steel tubes that certainly couldn't break down a door and could only break bones intentionally and with effort. You rarely see them deployed, which is unfortunate in my opinion, because it is an escalation of force step designed to counter physical but non-life-threatening aggression. So essentially you're abandoning a spectrum of force and adopting a model of only two modes - subjugated or dead.
